Abstract
Exclusive differential cross sections for the (γ,nO process have been measured for =150, 200, and 250 MeV and =49°, 59°, and 88°. This measurement is the first of its type to be reported for the energy region above the pion production threshold. An uncollimated bremsstrahlung beam was incident on an O target, and neutrons were measured with a recoil proton spectrometer with resolution sufficient to identify the residual ground state. The results are compared to (γ,p) data and to calculations including effects from meson exchange currents.
